The most important difference is that full type information
is still available.  Other differences: array and structure
references are not decomposed, looping constructs are still
intact, variables have not been assigned memory slots.

Depending on how things work out, there might be call for
both SIMPLE and mid-level rtl.  We'll have to see.
